Antminer S1 power supply

[fractalbc]

Ive figured its prob cheaper and easier to go for 3 seperate power  supplies something like corsair 500w and then just have one per miner

That is a reasonable choice

3 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027 is 150 usd and is 85% efficient at half load ( http://www.plugloadsolutions.com/psu_reports/CORSAIR_CMPSU-500CXV2_ECOS%202415_500W_Report.pdf ) and you can turn them on and off individually and move to different circuits as needed.

1 x http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063 as posted in a different thread of the same title costs 250 and is a brand I don't really know.  But, it will be around 90% efficient at the loads you anticipate ( http://www.plugloadsolutions.com/psu_reports/ROSEWILL%20INC._LIGHTING-1300_ECOS%202330.1_1300W_Report.pdf ).  Will that 5% efficiency pay back the extra hundred dollars?

Now, if you are willing to spend 75 dollars per unit, http://www.newegg.com/Product/Product.aspx?Item=N82E16817151136 for a seasonic or http://www.newegg.com/Product/Product.aspx?Item=N82E16817182068 for a rosewell get you the same 90% efficiency at a total cost of 225 USD.

Half the fun of this hobby is figuring stuff out.

Thanks im in uk though and we dont seem to get these same brands as you in usa or the low prices

With the Rosewill 450W with free shipping, is 37A at 12v enough to power?

At $60 each, wouldn't be a bad deal - think it would push the PSU too much?

I wouldn't go with the lower rosewill's had a bunch sent to us for hosted machines most of them died in less than a week

I have 2 antminer S1 on a Corsair RM850, drawing 730Watt from socket (on 220VAC, 50Hz).
The RM850 can give 70A on 12V rail, so there is enough to spare (because 730 / 12 = 61A not taking into account the PSU losses).
So my conclusion is that a single S1 miner draws about 30A in 12V. A PSU giving 35A should be ideal (to hit max. efficiency).

At the moment I'm using only 2 PCIe cables with dual connectors to power the miners. Cables are cold/lukewarm.
But since the PSU has 5 connectors for 8PIN or 6+2Pci-e I will change this to 4 seperate cables (for some reason only 3 PCi-e cables are delivered with the PSU).

Is this sufficient for one Antminer S1 ?
will I need anything else beside the jumper (can I strip a copper ground wire and leave some shielding on, or is there a better way?)
Any other advice?

Thank you :-)

CX600 is fine, it's got 40A on 12V rail. More than enough.

It really is that simple...  Paper clip from green to black cable next to the green one.  You can also just google "power on psu without motherboard".

I would suggest you use decent sized "wire" and just cover with electrical tape to ensure safety.  Copper ground wire might actually be too big depending on the AWG, but try it.  I would say it should have some resistance to put in and take out but doesn't make your face red while doing it:)

I couldn't find a paper clip so I found one of those small black paper binder clips, took off one of the "levers" and bent the ends straight... it was some work but they fit and won't be going anywhere lol...

Anyone running two or three oc ant of one psu?  If so which ones?

Also do ants need modular or non modular type which is best?

thanks

I suggest one 800W bronze plus per OC ant...gets the best efficiency.  Efficiency will be important when connecting more than one ant to the same breaker.

This configuration should allow you to safely connect 3 ants to one 15A breaker.

Thank you for posting the question davida (glad to see fellow miners from "across the pond").
The mention of running  2 AntMiner S1s on a Corsair RM850 almost makes me want to upgrade, even before getting the 1st Ant in hand (terribly addicting this mining thing;-).
I keep seeing people post about "bobby pins" and "paperclips" dandirk so you're the deciding vote, if I'm in a pinch I won't feel so squeamish about it.
There isn't a reasonable computer store within hours of my location, if I could get the setup right on the first try and keep it running...that would be great.

Wishing y'all much luck too :-)

See the antminer setup guide and help thread here.

I bought the Antec 850 80+ Bronze and other then the motherboard wire there's a CPU wire, does it need to be connected somewhere? Or does it need to be jumped as well?

hi

just got my antminer s1 and corsair 500m up and running.  the 500m comes with the 2 pci e plugs on 1 cable, i saw this mentioned before that its not a good idea to run the 2 off 1 cable so im just running 1 blade untill i find a solution. which im hoping someone can help me with pls?

it has another 2 port that are 6 pin on the psu, are these pci-e ports? what can i do to supply the other blade? what happens if i run 2 blades from the 1 cable? im not to savvy when it comes to psus etc...

thanks for any help guys

Take a look at this Dabs offer 64 quid EVGA 650W SuperNOVA NEX650G 80+ gold rated fully Modular Power supply rated, we get stung with the leccy in UK and this would save you 20% on running costs over cheap ebay effort and if you register online with Evga free 10year warranty.

I have 2 RM750's powering 3 overclocked S1's.

Total wattage +-1100W from the wall and 4.8A

Hi, has this power supply ARTIC Fusion 550-EU  http://www.arctic.ac/eu_en/fusion-550rf-eu.html enough Ampere to power a Antminer S1?
It has +12V1 17A; +12V2 17A; Combined Output 408W
I have also an industrial power supply 12v 50A  http://www.andromedastore.it/home/art1/0/34727/26479/Alimentatore-switching-12v-50A.html can I use this instead a PC power Supply?

Thanks W_M

I bought a 525W cooler master power supply... it couldn't handle it and I needed to buy another to power the unit.

Make sure the 12 volt rail is rated for 500w +.

Simple math.  is 17 (the current on the 12v rail that feeds the pcie plugs) > 28 (the current needed by the antminer)?

I purchased one of the server PSU's from minersource.net (was very professional and fast - would highly recommend them).  I think for long term, that is by far the best solution, assuming you can stomach the noise - which is the only drawback I see.  Highly reliable and high efficiency, and an excellent value - only around $80 to power two PSUs is great.

I'm running into a problem though, in that I might be in a situation where I need to run 2 S1's short-term and need another PSU.  Its a long story involving an eBay buyer who has to wait to pay me etc..

I have a Corsair AX750, which is a gold PSU that I use to run my desktop - that I was considering trying to use to power the two S1's for a week or two - depending on how long this eBayer takes.  It has 62A on the 12V single rail, and enough PCI-X connectors.  It has also been supply two 7950's running overclocked, along with an overclocked i7 920 - faithfully and reliably.  Link to the stats:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139016

If I was going to be running these two until they aren't profitable to run anymore, I would defientely buy another server PSU.  I'm not really excited though about purchasing such a dedicated PSU - I suspect it might be difficult to resell on eBay after everyone is using the new 1Th units that come with a power supply.

What is everyone's thoughts on trying to use that unit for a few weeks?  It still is covered with several years of warranty, but don't wanna blow up a unit because of something silly.

Thoughts?

[JohanM]

I think the 62A should suffice for 2 ants. No OC'ing of course.Yuo'll be running at about 92-94% of max.
